TILE ROOFING.

SPECIFICATION forming'part of Letters Patent No. 517,832, dated April10, 1894.

Application filed March 3, 1893.

To all whom it may concern.

Be it known that I, GEORGE H. BABoooK, a citizen of the United States,residing at Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Tile Roofing, ofwhich the following is a specification.

The purpose of this invention is to reduce to the minimum the number ofdifierent sizes of tiles required to cover a conical roof; and

said invention consists in a series of interlocking tiles, wherein theunits or members are laterally adjustable upon one another, to embracedifferent circumferences in the conical roof, while preserving thenumber of tiles included in a circle and preserving their individuallateral dimension for a considerable number of tiers in the order oflaying.

The herein described tiles are vertically- 2o aligned in the order inwhich they interlock, and being convexed in the center, form, whenassembled upon a conical roof, lines of relief converging from the basetoward the apex of the cone, producing a highly ornamental z 5 effect.The feature of lateral adj ustability aforesaid, is adapted to preserveperfect uniformity of convergence in the said lines of relief. Owing tothe small number of difier ent sized patterns required, economy is efofected in molding and laying the tiles by reason of uniformity andinfrequent change'of selection.

Heretofore it has been necessary, in order to preserve the convergingalignment of the 3 5 tiles upon a conical roof, to manufactureespecially therefor as many difierent patterns of tile as there aretiers in the entire covering.

The herein described invention is so adapted that whether the circularseries composed 40 of a given number of tiles have a maximum or aminimum circumference, the weather joints will be maintained.

It will be obvious that what is herein stated With reference to tilingfor conical roofs is 5 applicable also to roofs having the form ofconical segments.

Referring to the accompanying drawings in which similar characters ofreference indicate corresponding parts in each view: Figure 1,

constructed according to my invention; Fig.

2, a horizontal section at a, a, Fig. 1; Fig. 3,

a horizontal section at b, b, Fig. 1. Fig. 4,represents a verticalsection enlarged, taken at 0coc, Fig. 1; Fig. 5, aface view of asingletile of one dimension of pattern; Fig. 6, a face view of a single tileof another dimension of pattern; and Fig. 7, a bottom end view of Fig.5.

The invention herein described may be practiced with the use of variousforms of tiles, but the form herein illustrated is more especiallyadapted for carrying out said invention. This form consists in thatsubstantially as represented in Figs. 5, and 7, of'approximatelyrectangular form, havinga downward flange f, extending about half itsperimeter below its axial line g, g, and an upward flange h, above itsaxial line extending the remainder of its perimeter, whereby it isadapted to interlock with adjacent similar tiles, as appears in Fig. l;and also having at its center, a raised or relieved portion forming aconical segment a. At either, side of the conical segment i, and uponthe flat portions 5, of the tile, the overlapping flanges f, of theadjacent tiles form laterally movable weather joints.

In Fig. 2, in which a series composed of a given number of tiles areassembled in a large circle, the joints on the surfaces j, are extendedto' the maximum, while in Fig. 3, wherein the same number of tiles of asimilar dimension are assembled in a small circle, the said joints uponthe surfaces j, appear as 8 5' contracted to the minimum; the cut outparts it, is, Fig. 7, allowing of the range of adjust ment. By means ofsuch adjustability in the weather joints a dimension'of pattern such asindicated in Fig. 5, for instance, used for several tiers upon theconical roof, shown in Fig. 1, commencing at the level a, at, until aconsiderably higher level, say at b, b, is reached, when the nextdimension of tile of marked difierence, as in Fig. 6, is used 5 inlaying from b, b, to c, c, d, d, and e, e, without affecting the uniformconvergence in the vertical alignment of the tiles as they appear inFig. 1, when the roof is completed.

According to the extent of lateral adjust- 10o may be ability providedin the design of tile adopted, a less or greater number of difierentsizes may be used to fill the roof. The minimum of contraction in thelaterally adjustable joints of the dimension of tile represented in Fig.5, is equal in fitting capacity to the maximum of expansion in thelaterably adjustable joints of the next dimension of tile, in Fig. 6, inthe order of laying.

When two or more vertical series of tiles are placed together, as inFig. 1, so that the tiles of one series overlap at or about the middleof the lengths of the adjacent series, the planes of the interlockingedges of the said one series lie intermediate to the planes of theinterlocking edges of the next; the range of adjustment in the movablejoints being limited only by the form, or possibly the entire width ofthe tile, should the same have a fiat surface.

I claim as my invention 1. A tiling for conical roofs, consisting of theherein described series of interlocking tiles wherein units or membersare laterally adjustable upon one another whereby; several tiers ofvarying circumferences are composed of differently adjusted tiles ofuniform lateral dimension.

2. The herein described roofing tiles, adapted when assembled inoverlapping vertical series, to overlap at or about the middle of thelengths of the adjacent vertical series, provided with adjustable jointsat those edges which in one said series lie in planes intermediate tothe planes of the edges in the other said series.
